IMPROVED STONE PAVEMENT;

specification formmg party Letters Patent No. 85,814, dated January 12, 1869 -To all whom it'uzayconcern:

.Beit knownthat If, CHARLES JGUIDE'I, of the city, county, and State ofNew York, have new'alnd useful Improved Pave- 1 ment; am I do herebydeclare the following 'i n vented to :be a clear, full, and exact description of the same, sufficient to enable others skilled in the art to which my invention appertaius to fully understand and use .the'same, reference being had to the accompanyingdrawings, making part of this specification, and in which- -"-l1igure1 represents a longitudinal section of this invention. Fig, 2' is a plan or topview' thereof. h -l.Similarlet-t ers of reference indicatecorresponding parts in the two figures.

This invention'relates-to a pavement whichis composed of stone hlocks t'orming parallel- .opipeds, the narrow ends or edges of which;

are cut smooth, while their broad sides are cut purposely uneven, or rugged, the tonedees-of said broad sides beingcha 'e ed oil in such a manner that said blocks, whenput together, form close joints at their narrow en-ls and. open joints at the broad sides, and 'a pavement is obtained which offers a good foothold for the draft animals, and at the same time a smooth surface-for the wheels passing over the same.

A-represents a section of my pavement, which is composed of a series of stone blocks," B. Thes'ehl'ocks are cut in in the form of parallelopipeds, unlike the blocks used in what is known as the Russ or Belgian pavement, which are out in the form of inverted truncated pyramids, and, furthermore, the narrow edges orends a of my blocks are.

. eutsmooth, .while the broad sides or surfaces 1) thereof are purposely'cutrugged or uneven,aud .the top edges of these broad sides are chamfered-ofi', assho'wn at 0, Fig.1.. If'two inverted truncated pyramids,'as used in the Russ;or'Bel'- giau pavement,-are' placed side by side, a close joint is formed on the top surface,and thepavement thus produced ofl'ers no foothold to the draft animals. But by placing a series of my bloeksB together, as shown in Fig.2, the joints between the smooth-narrow edges a,'whi,ch run parallel with the sides of thestreet, become close, while the joints formed-between thebroad rugged surfaces b, with-the ohamfered edges 0, which joints run transversely across the street,-h ecome open and-a pavement is formed which ofi'ers a 'firnl hold to the draft animals, while it presents a jsin'ooth surface to the wheels'passing over it. Theopen 'joints left between the rugged surfaces 0 of the blocks are filledwithsand, and the pa\-'eluent-be comes perfectlyv firm and'solid, and the single blocks are not liable to work loose. r

I do not claim broadly as invention a pavement composed of l)loel sinadein the form of parallelopipeds; but

-What-I do claim, and desire to secure by Letters Patent, is-

A pavement compos'edof stone blocks,

' made in the form of parallelopipeds, having their narrow edges or ends cut smoothand their broad sides purposely out r'uggedor uneven and with ehamfered edges, substantially as and for the purnose described.
